upper '1 checker ll; w 1c kitchen o the l to check the food see that it coren ordered and mil 0; r or the on;

room 1 "ilillll l in i in ed check such as shown in Fig. 2. The waiter takes the order to the kitchen, where it is filled. He then returns with the food and stops at the checkers desk. The checker places the check in the machine and then depresses the keys representing the waiters number. These keys are so constructed that they will remain depressed until either a release key or another waiters key is depressed, so that it is only necessary to depress the waiters keys on the first entry of the series.

The pricev of the. item is then entered by depressing the proper amount keys. The machine has a bank of keys in which the 5-eentkey is located, and another bank of keys in which the values of all of the keys end in o-cents. A third bank is also pro vided, which contains all the even dime keys, that is, the 10, 20, 30, 10, 50, 60, 70, 80 and 90 cent keys. Depression of a key in any 01 these three banks controls the release mechanism of the machine, so that it will be released and the circuit closed through the electric motor, which will immediately operate the machine. A lock is provided for each checkers key, so that the checker on duty can depress and lock her key in depressed position when she first takes her place, and maintain itdepressed until she eaves, so that it is unnecessary to depress this key on every operation.

It the amount of an item is in even dollars, such for instance'as the first item on the facsimile of the check shown in Fig. 2, it is necessary-to press a special release key R- which will release the machine for operation.

It sometimes happens that food is returned, and when this occurs the procedure is as follows: the check on which the order was originally placed is inserted in the mechine and the machine released by the above mentioned release key, which prints a plurality of Zeros over the previously printed amount corresponding to the goods returned. This is shown in the bird item in Fig. 2. The card is then removed, turned'over, and reinserted in the machine, the price of the goods returned is set up on the amount keys, and the Void key is depressed, whereupon the amount and the word Vo d are printed on the back of the slip, as is shown in Fig. 3.

There are only two totalizers used in the present machine. One of the totalizers, which will be known herein as the Total service totalizer, is engagedv with the actuating mechanism on every adding operation.

'The other totalizer is what is known in the art as an adding and subtracting totalizer, that is, it has both adding and subtracting pinions which are capable of being moved into engagement with the actuating means. It will be known herein as the Net service totalizer. Normally the adding elements of this totalizer are in position to be engaged by the actuating means so that amounts set up on the keyboard are normally added into this totalizer. hen, however, the Void key is depressed, the totalizer is automatically shifted so that the subtracting pinions thereof are in position to engage the actuating means and the adding elements are retated baekwardly to the extent of the amount set upon the keyboard, as will be more iully described later on.

Waiters key s.

There are provided herein three banks of waiters keys (Figs. 1, 17, 18 and 19). These keys of each bank are slidably mounted in a key frame 26 supported by two rods 27 and 28 carried by the machine side frames in a manner well known in the art. Each otthe keys 25 has a shoulder 29 formed thereon adapted to cooperate with a pin 30 carried by a detent 31 supported by links 32 and pivoted to the key trame 26 (Fig. 17). When any of the waiters keys 25 is depressed, the beveled face 01 the shoulder 29 will move the detent 31 downwardly until the shoulder on the key has passed the pin, whereupon the detent will be returned to its normal position by a spring 66 to be later described, and will thereby hold the key in its depressed position. it locking plate 34; (Fig. 19) is also provided which is identical with the locking plates shown in the patentto Fuller No. 1,242,170, granted Oct. 9, 1917, for the purpose of locking the keys in their depressed position during an operation oft the machine. In 19 the locking plate 34; is shown in its normal position. At its upper end this detent is pivoted to a link 35 which has a. slot 36 cooperating with pin 37 carried by an arm fast on a release shaft 39. hen the machine is released, as will be hereinafter described, the release shatt 39 is rocked counter-clockwise Fig. 19), which moven'ient, through the slot and pin connection above mentioned, will rock the link clockwise and will move the locking plate 3 1- upwardly so that one of a plurality of hooks 10, carried thereby, which. corresponds with the key depressed, will engage a pin 11 carried by said key, and thereby lock the key in its position. The hooks 10 correspondingto nndepressed keys will be moved beneath the pins 11 and will thereby prevent any of the undepressed keys from b ing dept f til the mechanism is again in its home position.

Means are provided to prevent the role; of the n'iaciiine unless one or more of the waiters keysis depressed. Fast on the release shaft 39 is an arm 4-2 (Fig. 7) having a flange 4:3 so'ferined as to normally contact a pin carried by an arin' lti, fast a yoke 47, loosely mounted on sliatt 48 which is supported by the machine side frames. The link'32 which carries the upper end of the detent 31 previously mentioned has an extension carrying a pin 49 adapted to cooperthe ale

1n the position usually occupied by ihe uniis oi cents bank oi? keys there is a bank of keys 69 from i5 3 io 95 in mul.1i p cs of These keys cooperate with a delenl; 79 .(Fig'. which is identical with lhe del'ei'ii; 73 for the Even cents bank and the function of which will be presently descril'icd. As keys 69 are release key... this bank of keys is ."0 provided with a machii'le release bar iden real with machine release bar 76, but not shown herein. A link 80 identical with link 77 ca the upper end of the 'nachine release bar of this bank and cooperates with the release mechanism in a manner to be later described.

Void bank.

The next bank to the right 1) will be known herein as the Void bank. It contains the Sr/z key which is depressed when only five cents are to be registered. This bank also carries the Void key which is depressed when any article entered on the check is returned for credit. The other key in this bank is the Release key, which will be operated to release the machine when only dollars are entered and also to release the machinoon totalizing operations.

There are three release bars 81, 82 and 83 cooperating with this bank. In F i .e the left hand bar 81 is shown. in Fig. 5 the center bar 82 is i lustrated, while in Fig. 6 the right hand bar 83 is illustrated. It can be seen that due to the shapes of the notches or recesses therein the bar 81 will be operated only by the 59 key. The bar 82 will be operated only by the Void key, and the bar 83 by both the 593 and the release key, but not the void key.

The chief function of bar 82 is to n ntain the void key in its depressed position when it is depressed. This bar carried by the pivoted links 8 1 and 85. The link 8 1 has a nose 86, which, when the bar 82 is moved downwardly by the depression of the void key, is adapted to cooperate with a notch formed in an arm 87 which is loose on the release shait 39. The bar 82 will thereby be held in its lowered position, which will hold the void key depressed.

Near the end of an operation or the machine the release shaft 39 is moved clockwise (Fig. slightly past normal position and then co'uliter-clockwise to normal. An arm 88 is fast on this release shaft, and when the shaft is rocked clockwise as above described, the said arm 88 will come in to contact with a pin 89 carried by arm 87, andwill thereby disengage the notch in this arm 8'? from the nose 86 on link 8d and therefore this arm and the bar 82 can resume their normal positions, shown in Fig. 5, under the influence of spring 90, the action oi which is well unc erstood in the art; I

Checkers lacy s.

The extreme right hand bank (Fig. 1) are checkers keys 95. They control the settingup of the initial of the checker on duty in order to print the same on the detail These keys also con rol the setting ofthe indicator to expose the initial of the checker on duty in a manner well known in the art.

Each of the checkers keys is controlled by a lock with an insertible key which is given to the individual checker corresponding thereto. Like the other banks of keys the of the plunger 98. As shown in this figure,

the lock is unlocked and the ke 1 ma 1 be depressed. )Vhen, however, the appropriate key is inserted and the key barrel rotated thereby in a clockwise direction (Fig. 11), the plunger 98 will be forced outwardly and will pass beneath or above the lug 97 on the key appropriate thereto, which will lock this key against movement in either direction. That is, may be locked against depression during the absence the checker correspondin thereto, or it may be locked in depressed position, thereby making it unnecessary for the checker to press this key on every operation. A. disk 102 is fastened to the bottom of the key barrel by a screw 103 and a pin 10% and has recess in its periphery (Fig. 1 1) which receives a pin 105 projecting downwardly from the frame. When the key barrel is turned, the disk102 is carried thereby and when the end of the recess thereof comes into contact with the pin 105 the movement ofthe key barrel will be stopped in the correct position.

P cleanse mechanism.

As is well known in the art, and shown in Fig. 21, the release shaft 39 is constantly under the tension of a spring 110, which is compressed between the en d of an opening 111 in a link 112, and a should formed on each of a pair of pilot guides 113. These guidesare pivoted to an arm 114 fast on the release shaft 39. The spring 110 will, when the shaft is released, rock it clockwise (Fig. 21) until a nose 115 oi the arm 11 1 comes into contact with a pin 116 on the side frame.

Fast on the release shaft 39 is an arm 117 (Fig. 4) carrying a pm 118 which normally rests just beneath an arm 119 fast on a hub 120 loose on the release shaft Three bifurcated arms 128 (see also Figs. 8, 9 and 15) are carried by a yoke 129 to which is also fastened the arm 123. It can be seen that whenever a key is depressed in the even or odd cents ban is the release bar appropriate thereto will be moved downwardly, which will rock the link 77 (Fig. 9), or the link 80 (Fig. 8), or the link 130 (Fig. 6), counter-clockwise, corresponding with the bank in which the key is depressed, this movement through mechanism to be presently described rocking the yoke 129 and therefore the arm 123 clockwise 4c) l ar enough to remove the arm 123 from the path'oi? a half-round stud.

carried by a downwardly extending arm 121 (Figs. 4 and 15) of the hub 120. This stud 122 normally contacts the flat end of arm 123.

As long as the stud 12 contacts the arm a the arm 119 will'prevent the rocking of the re shaft 39 due to the engagement of h the pin 118 on arm 117. Vhen to be released. however, the arm 123 is rocked clockwise by depression of a key. in the manner to be presently described. far enough to remove itfrom the path of the pin whereupon the spring 110 will rock the release shaft 39 counter-clockwise (Fig. 4), and the stud 1.22 will assume a position between the arm 123, and an arm 124 loose on shaft 48 and connected to arm 123 by a spring 125.

The means for rocking the arm 123 will now be described. This movement is accomplished. by the depression of a key in the even cents bank. a key in the odd cents bank, or either the fig: key or lease key in the Void bank. It will be recalled that both the even and odd cents banks ar provided with release bars. These bars are pivoted to links 77 and 80 re ectively above mentioned. Each or the links 77 and 80 and a similar link 130 for the Void bank has a projection 126 (Figs. 6. 7. 9 and 15) carrying a pin 127 each of which is embraced by one of arms 128, fast on. the voke 129 loosely mounted on shaft 43. TV on hue of the release bars 76 or 83, 1s moved the yoke 1.29 will be rocked clockwise and therefore the arm 123 which is fast thereon will he rocked out of the path of the stud 2 on arm 121 and the release of the ma chine will thereby permitted.

Restoration 0 f release mechanism.

end of the operation of the ma e'ease shaft 39 is rocked counter- (Fig. 21) slightly beyond normal position and then clockwise to normal. This moven'icnt is accomplished in the following manner. Mounted on the right hand side frame of the machine is a gear 135 which meshes with another gear 136 fast on the end of a. shaft 137, supported by the machine frames. and which is the main drive shaft of the machine. The gear 135 also meshes with a small gear 138 which is directly connected with crank handle 139 used to operate the machine in the absence of the usual electric motor.

The large gear 135 receives only a one-half rotation upon every operation of the machine. Cut in the side of this gear is a cam groove 140 with two identically formed nodes 141 diametrically opposite each other. Pivoted on a. stud in the side frame is an arm 143 c wying at its end a pin 144 projecting through an opening 145 in the 111111 112. The '"n 143 a so carries a roller 146 cooperating iii n g: ove 14 V L is evident from the above that near the end of the one-half rotation of gear 135 one of the nodes 141 of slot 140 will cooperate with the roller 146 and rock arm 143 clockwise. This movement of arm 143, through the engagement of pin 144 thereon with a shoulder 147 formed in the opening 145 of link 112, will cause this link to be lowered. This meven'ient of the link 112 will rock arm 114 and release shaft 39 counter-clockwise slightly past normal and then back to normal.

hen the release shaft 39 is rocked clock- .vise (as seen in Fig. 4) the pin 118, previously described, carried by arm 117 comes into engagement with a surface 148 of a restoring lever 149 loose on shaft 48. This lever has a. tail engaging with an extension of the stud 122 (Fig. 15) so that when the release shaft 39 and arm 119 are rocked clockwise (Fig. 4) the restoring arm 149 will also be rocked clockwise. The tail thereof Will force the arm 121 clockwise far enough to permit the arm 1-3 to be returned to its normal position with its end in engagement with the hal=fround stud 122, whereby the release shaft 39 is held against rotation until the machine is again released.

D'ifi'erentz'al mechanism.

With a few exceptions, which will be hereinafter pointed out, the differential mechanism of this machine is like that of the patent above referred to. For this reason, only a very brief and general description thereof will be given herein.

As can be seen from Figure 9, each differential unit is driven by a pair of cams 161 which coperate with a pair of rollers carried by a Y-shaped lever 162 which is pivoted to the differential unit supporting frame 163, as is Well known in the art. All of the differential units are supported on two rods 164. At its upper end the lever 162 is connected by a link 165 to a driving segment 167 pivoted on a. bushing 168 mounted in the supporting frames 163.

The cams 161 are fast on shaft 137, which is the main drive shaft of the machine, and which receives a complete counter-clockwise rotation (Fig. 9) at each operation of the machine. The rotation of the cams 161 rocks the Y-shaped lever 162 counter-clockwise and then clockwise and therefore the driving Segment 167 is moved first counter-clockwise and then ClOCKWlSO by means of the link 165.

Also loosely mounted on the bushing 168 is a substantially circular totalizer actuator 17 0 having teeth 171 adapted to be engaged with and drive the selected totalizer wheels. The totalizer actuator 170 carries a link 172 and a bell crank 173 which in turn carry a. latch 174. This latch normally rests on a shoulder 175 out in the driving segment 167 and causes the totalizer actuator 170 to be moved with the driving segment 167. As the totalizer actuator 170 moves upwardly, the

outer end of the bell crank lever 173 will come into contactwith the inner end of whichever one of the keys of its appropriate bank has been depressed. This will cause the latch 17% to be disconnected from the shoulder on the driving segment 167 so that the totalizer actuator 170 will stop in a position commensurate with the value of the key depressed while the driving segment 167 will continue its movement to the full extent. When the latch 174 is disconnected in this manner the forward end thereof engages one of a plurality of notches 176 formed on the inner periphery of a segmental plate 177 carried by the differential supporting frames. l Vhen the driving segment 167 is given its clockwise movement to normal position, a surface 178 thereof comes into contact with a pin 179 carried by the totalizer actuator 170 and moves this actuator in a clockwise direction to its home position. Springs (not shown herein) are provided for returning the latch 174; to its normal position in contact with the shoulder 17 5 when the shoulder comes opposite the rear end of the latch on its return or clockwise movement.

It will be rememberec. that in the present machine there is a bank of Even cents keys, that is, 10, 20, 30, etc., and also a bank of Odd cents keys, that is, 15, 25, 35, etc. The differential mechanism appropriate to the even cents bank of keys will operate in the normal manner, as above described and as is very well known in the art. A; slightly different construction is necessary, however, in the odd cents bank. In this bank a permanentstop 180 (Fig. 8) is provided in the 5 position, to control the differential in the Odd-cents bank so that the bell crank 173 for this bank will come into contact with the step 180, to disconnect the totalizer actuator in the 5 position when a key in this bank is depressed, or when this difierential is released for operation by depressing the 5 key in the first bank. This will cause the latch 17st to be moved (Fig. 8) until the end thereof occupies a notch n the stop 180. This stop is placed opposite the 5 position on the keybank, so that when the differential mechanism for the odd cents hank is operated it will register 5. As can be seen in Fig. 7 the latch 174 for the odd cents bank is so located that it cannot contact with the inner ends of the keys deprcssed'in this bank and therefore the depression of one of the odd cents keys will have absolutely no eflect upon the differential mechanism appropriate thereto, as the latch for this mechanism disconnected from its driver by the permanent stop 180.

From the above it on n be seen that nponthe depression of a key-in the odd cents bank, 59':

of the amount appropriate to thekey depressed will always he registered upon the units wheel of its corresponding totalizer by means of the units difierential mechanism ap propriate to the odd cents bank. It is, however, necessary to register the tens on the tens wheel of the totalizer under the control of the key depressed in the odd cents bank. in other words, if 45 is to be registered, the key will be depressed in the odd cents bank. The differential mechanism appropriate to this bank will register 59?, due to the permanent stop 180 carried by this bank, and 404;: will be registered on the tens wheel f the totalizer by the differential mechanism appropriate to the even cents bank. This is done in the following manner The bell crank 173 for the even cents bank has a laterally extending stud 181 (Fig. 7), the extreme end which lies in the same vertical plane as the keys of the odd cents bank. It is apparent from an inspection of Fig. 7 that when a key is depressed in the odd cents bank, the extension 181 of the bell crank 173 will strike the inner end of the depressed key and cause the latch of the differential mechanism appropriate to the even cents bank of keys to be discoi'mected in the position appropriate to the key depressed in the odd cents bank.

The differential mechanism appropriate to the void bank is practically the same as that shown in Fig. 9 and used in connection with the even cents bank. Duplicate reference numerals will be used in Fig. 4 to describe duplicate parts. A driving segment 167 is rocked first countebclockwise and then clockwise by means of a link 165, a Y-shaped lever 182 and a pair of cams 161 fast on shaft 137, as has been previously described. Differential mechanism for this bank is provided with a latch 174: mounted on an arm 172, and a bell crank 173 and engaging a shoulder on the driving segment 167. The bell crank 173 and the arm 172 are pivoted to an arm 182 which in this bank takes theplace of the totalizer actuator 17 0, shown inFig. 9, there being no necessity for the said actuator in this Void ban.k,as this differential mechanism does not actuate any totalizer elements. The latch 174: for this bank is adapted to be disconnected from its driver by contact with the inner ends of the Void key only shown in Fig. 4. The 5-cent key and the release key B do not displace the zero stop pawl for this bank, thus when either of these two keys is depressed, the differential is stopped by said zero stop pawl.

Operation of zero stop pawls.

Vfhen the 5g: key in the Void bank (Fig. 41), is depressed its bar 81 is moved downwardly. This bar pivoted to an arm 184 which is mounted on the key frame. This arm cooperates with a pin 185 projecting laterally from anarm 186 (Fig. 16), fast on a short shaft 187 carried by thekey frame of the Odd cents bank 8). Also fast on this shaft is a zero stop pawl 188 such as is well known in machines of this type. It is the function of this pawl to disconnect the latch of the Odd cents diiferential mechanism in its zero position if no keys in the bank are depressed.

It can be seen however that when the Sc key is depressed the movement of the bar 81 will rock the arm 184 counter-clockwise, which will rock the pin 185 arm 186, shaft 187 and zero stop pawl 188 clockwise (Figs. 8 and 16). This movement of the zero stop pawl 188 will permit the latch of the Odd cents bank to move up live steps and contact the permanent stop 180, above describec to register 5 on the appropriate totalizer wheels.

It is evident that when any key in the Odd cents bank is depressed both the zero stop pawl 188 for this bank and the pawl 189 for the Even cents bank must be moved to ineffective position. The pawl 188 carries a. pin 190 which projects to the right (Fig. 16) and lies in the path of a plate 191 riveted to the side of an arm 192 which is pivotally connected to the detent 7 9 for the Odd cents bank. Thus it can be seen that when the detent 79 is lowered due to the depression of a key in tl bank the arm 192 will be rocked clockwise. As the plate 191 is fast thereto it will rock the pawl 188 to its ineffective position and permit the latch of the Odd cents bank to move up and contact the permanent step 180.

t is also necessary to rock the pawl 189 appropriate to the Even cents bank to its ineffective position when one of the Odd cents keys is depressed, as the differential. mechanism of the Even cents bank registers the tens of the amount to be entered. \Vhen. therefore one of the Odd cents keys is depressed and the arm 192 rocked, as above described. this arm comes into contact with a pin 194 projecting laterally from an arm 195 fast on ashort shaft 196 carried by the key frame for this bank. The zero stop pawl 189 is also fast on this shaft so that when the arm 192 is rocked counterclockwise the move ment is transmitted through arm 195 and shatit 196 to the pawl 189, which is thereby moved to its ineffective position.

Total'z'sers.

In this machine only two totalizers are necessary. The totalizcr on the back line, which is the Total service total zer (Fig. has one totalizer wheel 210 for each denomina-- -ronnding a shaft 219 supported tional order. In its normal position. it is alined by an alining bar 211 which extends across aii of the wheels. This aliner is rocked out of engagement from the totalizer Wheels when these wheels are moved into engagement with the actuators by means shown and described in the before mentioned patent.

This totalizcr rocked into engagement with the art ators on every operation except a Void transaction. The means for controlling the engagement of this totalizer are not shown herein as they are well. knownin the art.

The Net service totalizer, which is located on the upper totalizer line, is identicah ly the same as that shown in the patent above referred to. It has an adding wheel and a subtracting wheel appropriate to each d enom inational order. Each wheel. has fast to its side a bevel gear and located between these wheels and mesaing with the bevel gears on both are two bevel pinions 213. The effect of this construction that the wheels of each pair move in opposite directions. On adding operations the set of adding wheels is rocked into cngz g ment with the actuators. On Void operations however, that is, where food is returned for credit, the totalisaer shifted laterally so that the subtracting wheels are placed in p0 11 to be engaged. \Vhen these wheels are with the actuators and rotated in a 1 i i direction. the adding wheels will he reversezy rotated to the same extent, thereby subtracting the amount of the Void transaction from the adding wheels.

It is e idcnt from the above that the difference between the totals on the Total service totalizer and the Net service totaliz-er is equal to the total amount of the void transactions.

The usual mechanism s pro ided for "insferring from lower to higher (lOIlOlnl orders. As this mocha herein.

I mlz'catom.

This machine is provided with the usual indicators. They are not shown herein they form no part of this inv nt on. The indicators are set by the ai mechanism. Pivotcd to the TOTEM; actuator 110 is a beam 215 (Fig. 9). cl l of this beam is bifurcated and cooper with a pin it is pivoted at its upper end to toot 1 f2 st on one of a plurality of slee frames. At its lower end the link 2118 oted to an arm 220 loose on a rod 291 also ported h the ma chine side frames. oller 7 d by the Y-shapcd l-' 162 roo'oe ates with and moves the he ..i to ts prop position, as determined by the diiJLerenti-al mechanism, which movement will adjust the link 216 and segment 217 correspondingly. The segment 217 has rigid therewith a seg ment which adapted to set the indicators in a manner well known in the art.

Dfi'erem'ial aliasing mechanism.

The differential mechanism is alined by means of an alining bar 223 carried by plurality of arms 224; fast on a shaft 225. The bar is normally in engagement with the teeth of all of the segments 217 and thereby maintains them in alinement. During the first part of the operation of the machine the shaft 225 is rocked counter-cit :lnvise (Fig. 91) by mechanism not shown l ein This movement removes the bar 223 from the teeth of the segment 217 and permits the diil erential mechanisms to be set. It is then rocked into engagement with segment 217 and thereby alines the differential mechanisms.

Printer.

This machine is provided with a printer whlch is located in the front part thereof.

The type wheels are set up by the movement of the differential mechann-tms above described in the following manner. Loose on the rod 221. F1 9 but secured to the arms 3 7 220, are a plurality of spiral seg nits .5101. which mesh with spiral. pinions 32, each fast on a shaft 233 (Fig. 23) supported by a printer frame 23d (Fig. 2d) and by a bracket not shown) carried by a frame 235. Fast on the forward end of each of the shafts 233 is segnient 236. These segments mesh with teeth formed on a plurality of racks 237 which are slidable transversely of the machine on three studs 238. It can be seen from the above description that when the diiferential mechanism. of the cash register is moved to its various differential extents, the movement will be transferred by means of the beams 215, links 216, arms 220, spiral segments 231, spiral pinions 232, shafts 233 and segments 236 to the racks 237, and therefore these rack will be differentially adjusted'in accordance with the depression of the keys on the keyboard.

The racks 237 have teeth 239 which mesh with pinions 2&0 faston the inner ends of a plurality of nested sleeves 24:]. 2% and The sleeves 241 supported by two long studs 24-2 projecting from the frame and supported at their forward ends by a plate 2&3. Attheir forward ends the various tubes 241 carry pinions 2 14 which mesh with type wheels 245 supported by long studs 246 projecting from the frame 234. It can be seen from the above that the differential movement given the racks 237 will, through the pinions 240, tubes 2911 and pinions 24%, pro )erly adjust the type wheels 2%" in accorc ance with the values of the keysdepressed. As seen in Fig. 25 there are two lines of type wheels, one above the other, and these two lines are set up simultaneously by the pinions which mesh with both lines of type wheels The upper line is for print.-

ing upon the detail strip, while the lower line will print upon an inserted check.

The printer is driven by the cash register and is provided with a main drive shaft 250 27 which is given one complete counter-clockwise rotation upon each adding operation of the cash register ineclianism which is not shown herein but which old and well known in machines of this type and illustrated inllnited States Letters Patents, ilos. 1,39%,256 and 1,619,796, granted to F.

It will be noticed that the nextto Emir the last item has a capital V printed beside it. This indicates that this amount is void and has been subtracted from the net service total, as above described. The last item shown on the strip is the total. of the amounts entered by checker A, the X, indicating that the total has been printed but that the totalizer has not been cleared. he detail strip 251 (Fig. 27) is carried upon a storage roll 252 supported by the frame 23%. It passes from the roll about a roller 253 carried by a lever and then extends over a rod which is the pivotal point of the platen. From the rod the strip passes about a roller 256, a second roller 257111151. a third roller 258 and then extends toward the left until it passes about a roller 259 carried by an arm 260 from which roller it is wound upon areceiving roll 'lhe strip is given a step-by-step feedir n flenient from the storage roll to the Z'QC 3l\1llg roll by niechanism not shown herein but which is old and 1 known in this art and shown in the Y, i teiy men above mentioned Shipley Patent, No. 1,619;

F: st to the inner one of the two arms 26;: is a longer arni 270. to which is pivoted a link 271. pivoted at its lower end to a lever (see Figs. 27 and The lever 272 is loosely mounted on a shaft 273 supported by the printer i i-nines, and at its left hand end is forked.

As these cams cooperate (Wreck printing mac/tou ism.

The waiter presents to the checker the custoiners order and this then inserted in the machine by the checker and the amounts of the various items thereon are printed opposite each of said items on the check. can be seen in Fig. 2. The check is placed upon a table 280 (Fig. 2'?) which may be provided with any suitable. guiding means for facilitating the printing upon the lines of the cheek. No means is provided for feeding the check between OPGl'iltlODS of the machine and it is necessary for the. checker to position the check properly, with relation to the guide, after each operation.

The impression on the check is made from the lower set of type wheels in the following manner; A resilient platen 282 is carried by a U-shaped bar 283 supported by a pair of arms 28% and 285 (Figs. 27 and 28). The arnn; 28%!- and 5285 are loose on the shaft and are connect-ed together by means olia yoke 286. The arm 284 has an extension carrying a pin 287 which normally lies just above the end of an arm 288 which is Fast. on the shaft 273. The arm 288 is held, in contact with the pin 287 by a spring; 289 extending from the pin 287 to pin carried by an '1 5290 of the arm 288. Also fast on the. shaft. 273 is a lever 291 which has a roller 292 cooperatingwith the periphery ot a cam 293 to st on a sh att 9.94:. The roller 292 held against the periphery of this cam by means of a powerinl ipring E295 stretched between a dmvnwardly c: inc; arm of the lever 291 and a pin on the frame. The shaft 294 is given a corridorclockwise rotation by a train ot gear-i 9;. not completely shown herein. but which is shown and described in the previously incntionml Sliipley patent. The can! rocks, the lever 291 slralt't/Q'Z'S. and arr: 288 ClOCiPXl. and the platen 282 will be lowered under the influence of gravity (rid the spring 289. The mechanism so do .e'ned that when the extreine) high point of the cam 293 no rs the roller. a. nose 296 formed on the end (it-the lever 291 will. engage the surtacc of the earn and raise the roller therefrom. As the cam Continnes its rotation, the nose 296 will suddenly drop from the high portion of said cam and when this occurs the lever 291. shaft 273. arnl 288. arms 28 1 and platen 282 will be given a very rapid counter-clockwise rotation under the inflnence ot the power Lil sprii'lg 5295 which has ween stretched by tie action of the cam 293. This rapid counter-clockwise movement of the platen 282 will bring it violently into contact with the lower type wheels and will therefore cause an impression to be made therefrom on the inserted check.

On certain operations such totalizing and subtotalizing, it is not desired to have a check in the machine and mechanism is provided so that when this occurs the downward or clockwise movement of the platen is pre vented, so that when the arm 288 and lever 291 are given their rapid counter-clockwise rotation by the spring 295 it will have no effect upon the platen 282. This mechanism will now be described. The table 280 .is formed with an openin therein through which feeling arm 300 27) adapted to This arm is pivoted on. a stud 301 and has a bifurcated portion surrounding; a pin 302 on a pitmanBOiS. At its righthand end this pitman is pivoted to an arm S04, which under certain conditions, is adapted to be moved to a position in which end lies beneath a toe2-05 carried by the platen-sujporting fran'i-e -83. At its opposite end the pitman 8 is bifurcated and is adapted to slide on the'shaft 250. It carries a roller 306 which cooperates with the periphery of a cam 307 on the outer end of the shaft 250. This cam is of course given a counter-clockwise rotation on each operation of the shaft 250. The pitman 303 tends constantly to move toward the right, due to the action of a spring 308 fastened at one end to the said pitnian and at the other 7 l end to the frame of the machine.

It can be seen that as soon as the high portion ofithe cam 307, which is normally in engagement with the roller 306, is moved away therefrom the spring will cause the pitman to move toward the right. As the feeling' arm SOOis connected. to this pitinan it will be rocked in a COLllltGY-ClOClUVlSG dir .etion and the end thereof will pass upwardly through the opening in the table 280. If there is a check in the machine the feeling arm 300 will come into contact with the bottom thereof and will be restrained against movement the spring 308 is not sufficiently strong to break the paper. if, however, there is no check in the machine, then the feeling arm 300 can pass upwardly to a greater extent and the pitman of course will be permitted to move a greater distance toard the right, as seen in Fig. 27. As the pit-man 303 is pivoted to the arm 30d it can be seen that this arm will be rocked counterclockwise about its pivot a snflicient distance to bring the upper end thereof beneath the toe 305 carried by the lower platen frame 283 an d therefore any downward movement of the platen frame will be prevented and no impression will be taken upon the check.

Ribbon mechanism.

An interlock is provided between. the total lever 320 (Figfil) and the amount lo which prevents d ression of any amount key when said total lever is out of its addi. position. When the total lever moved a shaft (31 (Figs. 4:, 9, 20 and 2i) will be rocked counterclockwise as seen in Fig. l. Fast on this sh are a plurality of arms 821 which carry a rod 322.

roe moven'ient of shaft 61 will place the rod in the path of movement of the lower ends of the arr which support the detents in the amount banks.

It is evident that when this occurs it will be impossible depress of the amount keys.
